## What is CVE-2024-21669?

CVE-2024-21669 is a critical vulnerability in hyperledger aries-cloudagent-python, published on 11 Jan 2024. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Hyperledger Aries Cloud Agent Python (ACA-Py) is a foundation for building decentralized identity applications and services running in non-mobile environments. When verifying W3C Format Verifiable Credentials using JSON-LD with Linked Data Proofs (LDP-VCs), the result of verifying the presentation `document.proof` was not factored into the final `verified` value (`true`/`false`) on the presentation record. The flaw enables holders of W3C Format Verifiable Credentials using JSON-LD with Linked Data Proofs (LDPs) to present incorrectly constructed proofs, and allows malicious verifiers to save and replay a presentation from such holders as their own. This vulnerability has been present since version 0.7.0 and fixed in version 0.10.5.

Weakness: CWE-347 (Improper Verification of Cryptographic Signature)

Affected packages and fixed versions:
- aries-cloudagent (PyPI): affected from 0.11.0rc1; fixed in 0.11.0
- aries-cloudagent (PyPI): affected from 0.11.0rc1; fixed in 0.11.0
- aries-cloudagent (PyPI): affected from 0.7.0; fixed in 0.10.5, 0.11.0

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
